scsi freezing problem with NetBSD current

["T. Makinen" <tjamaloo%gmail.com@localhost>]

Hello,

I had scsi freezing problem that has been discussed earlier here with NetBSD 4
running on Atari Falcon. I decided to try NetBSD current and it had
same problem.

It seems that scsi freezing happens because ncr5380 driver sets XS_STS_DONE
before calling scsipi_done(). Since 1.135 revision of scsipi_base.c,
scsipi_done()
bails out early if XS_STS_DONE is set.

Here is description why that check is implemented:

Leaving XS_STS_DONE out cures scsi freezing problem with my Falcon.
I tested this with NetBSD current (ncr5380.c,v 1.55).

Another issue is that I have to use loadbsd.ttp with -s option with CT63
accelerated Falcon to disable TT-ram, otherwise my scsi drive is recognized
to have just one sector with total capacity of 512K. Any ideas why
this happens ?
